Introduction - Alto Documentation

Overview

Agents are configured using a YAML file. The file should define:

The infrastructure to use (e.g., an EC2 instance)
Actions to perform within the infrastructure (e.g., installing custom Linux packages)
Your project’s dependencies (i.e., Python packages)
Your project’s entrypoint (i.e., what command to use to actually execute your project)
Environment variables
Files to download upon the project’s completion

Example

Here’s an example configuration file:

alto.yml

my_cloud_agent:
  infra:
    type: ec2  
    instance_type: t2.micro
    ami_image: ami-0889a44b331db0194
  requirements: requirements.txt
  entrypoint:
    type: script
    cmd: python <script name>.py --arg1 VALUE1
  env:
    ENV_VAR1: "{{ env('ENV_VAR1') }}"

Let’s break this down next.
